Epidemiology and Natural History of Perianal Crohn's Disease: A Systematic Review and Meta-Analysis of Population-Based Cohorts.

Approximately 1 in 5 patients with CD develops perianal disease within 10 years of CD diagnosis, including 11.5% who have perianal disease at presentation. Approximately two-thirds of patients require perianal surgery, with a smaller fraction requiring major abdominal surgery.

Safety of Immunizations for the Adult Patient With Inflammatory Bowel Disease-A Systematic Review and Meta-analysis.

Our study demonstrated that AEs after vaccination are mainly local or mildly systemic and do not differ significantly from the expected AE after recommended immunizations for the general population. Thus, gastroenterologists should reinforce that vaccines are safe in patients with IBD.

Strategies to Distinguish Perianal Fistulas Related to Crohn's Disease From Cryptoglandular Disease: Systematic Review With Meta-Analysis.

Limited high-quality evidence suggest that imaging characteristics may help discriminate CD from CGD in patients with perianal fistulas. Larger, prospective studies are needed to confirm these findings and to evaluate if combining multiple diagnostic tests can improve diagnostic sensitivity.

Epstein-Barr virus status and immunosuppression use in paediatric autoimmune liver disease.

Real-world data demonstrate that EBV serostatus is not routinely checked before immunosuppression for paediatric AILD. Lymphoproliferative disorder was not diagnosed in those with native livers; however, EBV IgG-negative LT recipients receiving EBV IgG-positive donor organs are at risk of early PTLD. Large multicentre studies with longer follow-up are required to further evaluate the risk.

Increased risk of hepatocellular carcinoma and mortality in chronic viral hepatitis with concurrent fatty liver.

Concurrent fatty liver was associated with a higher risk of HCC and mortality in patients with chronic viral hepatitis. Our results suggest the importance of management of fatty liver to reduce the risks of HCC and mortality in patients with chronic viral hepatitis.

Hybrid APC in Combination With Resection for the Endoscopic Treatment of Neoplastic Barrett's Esophagus: A Prospective, Multicenter Study.

Eradication and recurrence rates of Barrett's intestinal metaplasia and neoplasia by means of hybrid argon plasma coagulation at 2 years seem to be within expected ranges. Final evidence in comparison to radiofrequency ablation can only be provided by a randomized comparative trial.

Increasing Incidence of Cirrhosis Over the Past 2 Decades Among Children in Ontario, Canada.

In this first population-based study in children, the incidence of cirrhosis has increased dramatically over the past 2 decades.

Plasma IL-2 and Symptoms Response after Acute Gluten Exposure in Subjects With Celiac Disease or Nonceliac Gluten Sensitivity.

Symptoms do not reliably indicate gluten exposure in either subjects with CeD or NCGS. IL-2 production indicates a rapid-onset gluten-induced T-cell activation in CeD despite long-standing treatment. The effector site is unknown, given no increased intestinal permeability after gluten.

Quality of Care Program Reduces Unplanned Health Care Utilization in Patients With Inflammatory Bowel Disease.

Outcomes of IBD care were improved using a structured quality improvement program that facilitates small process changes, sharing of best practices, and ongoing feedback. Spread of these interventions may facilitate broad improvement in IBD care when applied to a large population.

Gluten intake and risk of digestive system cancers in three large prospective cohort studies.

Gluten intake was not associated with risk of digestive system cancers in adults without celiac disease. Restricting dietary gluten is unlikely to be beneficial to the prevention of digestive system cancers in the general population.

Prevalence of Forceps Polypectomy of Non-Diminutive Polyps is Substantial but Modifiable.

Inappropriate forceps polypectomy is common but modifiable. The proportion of non-diminutive polyps removed with forceps polypectomy should be considered as a quality measure.

Steroid-Free Deep Remission At One Year Does Not Prevent Crohn's Disease Progression: Long-Term Data From the TAILORIX Trial.

Achieving a sustained clinical remission off steroids with complete endoscopic remission in this cohort of 95 patients with early CD was not associated with less disease progression. Prospective trials to define the therapeutic goals that change the natural history of CD and prevent complications are needed.

Symptom Classes are Independent of Disease Severity in Decompensated Liver Disease.

Patient reported symptom severity occurred independent of disease severity, contrary to common assumptions. Focusing on the moderate and severe symptom classes as well as patients' history of ESLD complications may enhance providers' ability to improve symptom management for this population.

Dissection of barrier dysfunction in organoid-derived human intestinal epithelia induced by Giardia duodenalis.

Data suggest a previously unknown sequence of events culminating in intestinal barrier dysfunction upon G. duodenalis infection during which alterations of cellular ion transport were followed by breakdown of the tight junctional complex and loss of epithelial integrity, events involving a cAMP/PKA-CREB mechanism. These findings and the newly established organoid-derived model to study G. duodenalis infection may help to explore new options for intervening with disease and infection, in particular relevant for chronic cases of giardiasis.

Rome Foundation Clinical Diagnostic Criteria for Disorders of Gut-Brain Interaction (DGBI).

If this is the case, a lower frequency and a shorter duration (8 weeks or more) than those required for the Rome DGBI diagnostic threshold are allowed, provided that there is clinical confidence that other diagnoses have been sufficiently ruled out based on presentation and additional investigations as needed. Applying these criteria for clinical practice will allow the clinician to make a diagnosis, reduce unnecessary diagnostic studies and enhance the patient-provider relationship. Further research is needed to validate these recommendations.

Footprints of a microbial toxin from the gut microbiome to mesencephalic mitochondria.

Taken together, our results demonstrate that chronic exposure to dietary BMAA can trigger a chain of events that recapitulate the evolution of the PD pathology from the gut to the brain, which is consistent with 'gut-first' PD.

Influence of timing of maternal antibiotic administration during caesarean section on infant microbial colonisation: a randomised controlled trial.

We confirmed that microbiome colonisation is strongly affected by CS delivery. Our findings suggest that maternal antibiotic administration prior to CS does not result in a second hit on the compromised microbiome. Future, larger studies should confirm that antenatal antibiotic exposure in CS born infants does not aggravate colonisation impairment and impact long-term health.

International variation in oesophageal and gastric cancer survival 2012-2014: differences by histological subtype and stage at diagnosis (an ICBP SURVMARK-2 population-based study).

Survival from oesophageal and gastric cancer varies across high-income countries including within stage groups, particularly for localised disease. Disparities can partly be explained by earlier diagnosis resulting in more favourable stage distributions, and distributions of histological subtypes of oesophageal cancer across countries. Yet, differences in treatment, and also in cancer registration practice and the use of different staging methods and systems, across countries may have impacted the comparisons. While primary prevention remains key, advancements in early detection research are promising and will likely allow for additional risk stratification and survival improvements in the future.

Two microbiota subtypes identified in irritable bowel syndrome with distinct responses to the low FODMAP diet.

50% of IBS cases manifested a 'pathogenic' gut microbial signature. This shifted towards the healthy profile on the low FODMAP diet; and IBS P cases showed an enhanced clinical responsiveness to the dietary therapy. The effectiveness of FODMAP reduction in IBS P may result from the alterations in gut microbiota and metabolites produced. Microbiota signatures could be useful as biomarkers to guide IBS treatment; and investigating IBS P species and metabolic pathways might yield insights regarding IBS pathogenic mechanisms.

Bringing to Light the Risk of Colorectal Cancer in Inflammatory Bowel Disease: Mucosal Glycosylation as a Key Player.

Inflammation is a driving factor both in inflammatory bowel disease and cancer, but the mechanism underlying the transition from colon inflammation to cancer remains to be defined. Dysregulation of mucosal glycosylation has been described as a key regulatory mechanism associated both with colon inflammation and colorectal cancer development. In this review, we discuss the major molecular mechanisms of colitis-associated cancer pathogenesis, highlighting the role of glycans expressed at gut epithelial cells, at lamina propria T cells, and in serum proteins in the regulation of intestinal inflammation and its progression to colon cancer, further discussing its potential clinical and therapeutic applications.

Changes in intestinal barrier protein expression and intestinal flora in a rat model of visceral hypersensitivity.

The model rats of visceral hypersensitivity possess the decreased expression of occludin, ZO-1, AQP3, AQP8, and the increased expression of claudin-2 and claudin-4, meanwhile develop an imbalance of intestinal flora which probably increase serine protease activity, thereby activating the PAR2/ERK signaling and causing the intestinal barrier disorder.

Diurnal changes of colonic motility and regulatory factors for colonic motility in Suncus murinus.

These results indicate that the fundamental mechanisms of colonic motility in suncus are similar to those in humans and dogs, and we thus propose that suncus could serve as a novel small animal model for studying colonic motility.

Effect of amino acid-based formula added to four-food elimination in adult eosinophilic esophagitis patients: A randomized clinical trial.

The addition of AAF to a FFED did not lead to a larger decrease in PEC between baseline and 6 weeks, but may result in a significant improvement of QoL in adult EoE patients NL6014 (NTR6778).

Effect of chronic restraint stress and western-diet feeding on colonic regulatory gene expression in mice.

High-resolution colonic manometry interobserver analysis trial.

For the majority of motor patterns, the overall IOA for colonic manometry was substantial or high. This high level of agreement supports the use of colonic manometry application in clinical and research settings. Harmonization has the potential to improve agreement for long anterograde motor patterns with high amplitudes and for mixed direction patterns.

The herbal preparation STW 5 affects serotonergic pathways in the brain and colon as well as stress parameters in experimental irritable bowel syndrome.

The protective effect of STW 5 against RS-induced IBS is related to its ability to normalize the induced changes in 5-HT in the brain-gut axis and counteract the stress-induced oxidative stress and inflammation.

United States Healthcare Burden of Pediatric Functional Gastrointestinal Pain Disorder Hospitalizations from 2002 to 2018.

FGID hospitalization prevalence rates decreased recently, possibly due to national healthcare policy implementation. Nonetheless, constipation admissions increased. LOS was stable in recent years but associated costs-per-hospitalization were increasing over time, probably due to endoscopic procedures. More studies are needed to explain these prevalence and cost trends.

Menopausal hormone therapy and risk of biliary tract cancers: addressing the ant, not the elephant in the room.

Sex hormones are responsible for multiple physiologic processes by signalling through estrogen (ER) and androgen receptors (AR).(1) ERs and ARs are expressed in liver and biliary tract cells in normal and diseased states in both men and women. Thus, the liver is recognized as a sex hormone responsive organ. In general, estrogen is associated with hepatic "protection" while androgens associate with hepatic "progression".

BCLC strategy for prognosis prediction and treatment recommendation Barcelona Clinic Liver Cancer (BCLC) staging system. The 2022 update.

Treatment for hepatocellular carcinoma (HCC) has experienced major advancements since the last update of the official Barcelona Clinic Liver Cancer (BCLC) prognosis and treatment strategy published in 2018. Advancements in the field have emerged in al areas, but in this manuscript, we present those that have primed a change in the strategy and comment why some encouraging data in select interventions are still considered immature and in need of further research to gain their incorporation into an evidence-based model for clinicians and researchers. Finally, we describe the critical insight and expert knowledge that is needed to take clinical decisions in individual patients so that the recommendation takes into account al the needed parameters to allow a personalised approach.

Gut-derived systemic inflammation as a driver of depression in chronic liver disease.

The underlying mechanisms explaining the critical relationship between depression and cirrhosis remain to be fully elucidated. Several other psychosocial and biological factors are likely to be involved, and therefore the cause is probably multifactorial. However, the role of the dysfunctional gut-liver-brain axis as a driver of gut-derived systemic inflammation requires further exploration and consideration as a target for therapy for depression in patients with cirrhosis.

Digital health for functional gastrointestinal disorders.

In recent years, applications in digital health have created a new set of tools that can improve the care of these patients, including through improved symptom tracking, physiologic monitoring, direct provision of care, and patient support. Purpose The purpose of this review is to evaluate how digital applications are being used to manage functional gastrointestinal disorders today, with several examples of relevant technologies and organizations. It also the shortcomings of current treatment strategies and how they can be overcome.

Role of psychological questionnaires in clinical practice and research within functional gastrointestinal disorders.

The biopsychosocial framework as it applies to FGID has led to the inclusion of both psychosocial assessments in clinical management and research protocols. Future directions include the development of symptom-specific questionnaires for groups of FGIDs, culturally specific psychosocial questionnaires, and inclusion of psychosocial well-being as primary or secondary outcomes in clinical research trials. In this review, we aim to explore the role of psychological questionnaires in clinical care and research trials and share practical tips on incorporating a biopsychosocial framework in the care of patients with FGIDs.
